Twelve Bronx schools that deal with heavy-footed motorists are now eligible for the city’s first-ever speed cameras as part of a five-year pilot program approved by the State legislature.

The mobile cameras - clicking evidence for hefty speeding fines - will be affixed to a post along problematic school zones chosen by city transportation officials through a field study measuring how fast motorists generally travel within a speed zone. The cameras will rotate among different schools on a regular basis.

Cameras will take a picture of speeder’s license plate number as it zips above the posted speed limit. A ticket with a hefty fine will be sent to the vehicle’s owner.

“Speed cameras will be a big safety plus for our schools,” Bloomberg, flanked by officials including state Sen. Jeff Klein, who was prime sponsor of the legislation, said Tuesday, June 25 outside P.S. 81 in Riverdale.
